The UnregisterDuckNotification method deletes a previous registration by the application to receive notifications.
Pointer to the IAudioVolumeDuckNotification interface that is implemented by the application. Pass the same interface pointer that was specified to the session manager in a previous call to the IAudioSessionManager2::RegisterDuckNotification method. If the UnregisterDuckNotification method succeeds, it calls the Release method on the application's IAudioVolumeDuckNotification interface.
If the method succeeds, it returns S_OK. If it fails, possible return codes include, but are not limited to, the values shown in the following table.
| Return value | Description |
|---|---|
|
duckNotification is NULL. |
The application calls this method when it no longer needs to receive notifications. The UnregisterDuckNotification method removes the registration of an IAudioVolumeDuckNotification interface that the application previously registered with the session manager by calling the IAudioSessionManager2::RegisterDuckNotification method.
After the application calls UnregisterDuckNotification, any pending events are not reported to the application.
